REINFORCED EARTH

The design principle of reinforced earth is set forth and it is shown that the reinforcing action results from the friction between the earth particles and the reinforcing strips which must exist without slipping. It is shown how the granular friction on either side of the reinforcement takes place without slipping and with a factor of safety of S: dF/2Nd1 = f/S where dF is the increase in force over small distance d1 along strip; and N is the Normal stress in the soil. External stability and internal stability factors are discussed, and the choice of methods of design (UCLA-Rankine, Coulomb Force, Coulomb Moment, and a Reinforced Earth-LCPC method) are reviewed. The most heavily designed results are obtained form the UCLA-Rankine method. The bearing pressures should be calculated using Meyerhof's theory rather than the trapezoidal theory. Research is currently in progress to establish the exact position and development of the curve which delineates the failure zone from the restraining zone. The statement is made, however, that the failure zone is substantially smaller than the wedge. Details of construction are outlined.
